The Pacific Northwest Trail is 1,200 miles long, running from Glacier National Park in Montana to the Olympic National Park coast in Washington. I hiked it in 2015 and made the first ever documentary about the trail.
The full North Country Trail is 4,700 miles long, running from North Dakota to New York. I just hiked a 550 mile section of it across Michigan's Upper Peninsula. I broke the hike up into 9 sections and made an episode about each section.
